| Console over CDC ACM UART Sample |
| ################################ |
| |
| Overview |
| ******** |
| |
| A simple Hello World sample, with console output coming via CDC ACM UART. |
| Primarily intended to show the required config options. |
| |
| Requirements |
| ************ |
| |
| This project requires a USB device controller driver. |
| |
| Building and Running |
| ******************** |
| |
| This sample can be built for multiple boards, in this example we will build it |
| for the reel_board board: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/subsys/usb/console |
| :board: reel_board |
| :goals: flash |
| :compact: |
| |
| Plug the board into a host device, for sample, a PC running Linux OS. |
| The board will be detected as a CDC_ACM serial device. To see the console output |
| from the sample, use a command similar to "minicom -D /dev/ttyACM0". |
| |
| .. code-block:: console |
| |
| Hello World! arm |

| |
| Troubleshooting |
| =============== |
| |
| You may need to stop modemmanager via "sudo stop modemmanager", if it is |
| trying to access the device in the background. |
